| 摘 要： | 为提高小麦麸皮中阿拉伯木聚糖的得率,本研究在考察了温度、时间、碱液与H2O2浓度和振荡速度等单因素对阿拉伯木聚糖得率影响的基础上,采用二次回归正交旋转组合设计对阿拉伯木聚糖的碱提工艺条件进行了优化并建立数学模型。结果表明,在提取温度88℃、时间200min、NaOH浓度0.16mol/L、H2O2浓度1.5%的条件下,阿拉伯木聚糖的得率达到最大值21.23%,验证实验结果与模型预测值相符。 |

| Abstract: | In order to enhance the extraction yield of arabinoxylan from wheat bran,the effect of temperature,time,the concentrations of sodium hydroxide and hydrogen peroxide and shaking speed on yield of arabinoxylan were investigated.Based on this,the optimization of extraction conditions of arabinoxylan was carried out and mathematical model was established through the quadratic regression orthogonal rotary combination design.Results indicated that when the extraction temperature,time,the concentrations of sodium hydroxide and hydrogen peroxide were 88℃,200min,0.16mol/L and 1.5% respectively,the yield(Y) reached the maximum(21.23%),which was consistent with the validate experiment result. |
| Keywords: | arabinoxylan alkaline extraction orthogonal rotation combination design optimization |
